Application filed November I, BARNIML. Bnrmnno'r,

of Germany, residingat Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Knockdown Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beingha d, to the accompanying drawings,

,great exertion, and

and to figures of reference marked thereon, which form a part of this specification.

This invention relates to an improved knockdown box that is adapted to be assembled or taken apart quickly and without any provides a box or chestthat is convenient for transportation or storage;-' A box of this kind can be used for packing or storing goods, and when empty, can be knocked down or taken apart and laid away in, acompact forn1,/taking up but littleroom and it can be. used over and over again. j y

The box herein described is one that requiresno nails, or screws, or similar fastening elements thatpenetrate the material in putting it 'together, being made up of Side and end walls, or similar surrounding walls,

which are keyed together and which are held at their top and bottom edges by marginal flanges onthe top and bottom covers or plates.

The invention is illustrated in the accom panying drawings, in which Figure 1 is a perspective View of the box with its parts separated, the cover being omitted Fig. ,2 is an enlarged section on line 2, in Fig. 4. Fig. 3 is an enlarged section on line 3, in Fig. 4:,and Fig. 4 is a crosssection of the box when put together. Fig. 5 is a section'of a modified form taken at a point indicated by line 5 in Fig. 2.

I employ surrounding walls, varying in number according to the shape of the box,

' but I have illustrated an oblong box having end Walls and side walls 11 which are adapted to engage each other on their ends. The side walls 11 in the illustration, or the end walls if they are to go over the outside of the ends of the side walls, are provided with slots 12-on their top and botton' at a distance from t 'at n 1' Specification of Letters Patent.

their channels as wide as the thickness of the end walls so that they fit over the end walls and have their ends l l'fit in the slots 12 and also embrace the ends of the side walls. Wings 22 extend beyond the open end of the keys and are bent over at the ends to fit against the outside hold them against the end walls. fit 1n the slots 12 snugly and hold'the walls against transverse movement or movement in the planes of the sides of the box. A cover 15 and a bottom plate 16 have marginal flanges 17 and 18 respectively, which flanges are adapted to fit over the sides of the end and side Walls at the top and bottom and form closures for the box and also condeal the keys 13. d

When the box is to be asscml'iled, the bot tom plate 16 is laid down, then keys 13 are put at each end, and the side walls are placed vertically on the bottom with their slots over the ends 1 1 of the keys and are held spaced apart by the shoulder 19 adjacent to the end 14 on the-inner wall of each key. The end walls are then placed in the channels of the keys 13. Keys 13 are then placed at the top of each end wall with their ends in the slots 12 at the top of the side walls, and the box is held in'place rigidly while it can be packed with material. The cover is then put over the top and forced down over the outside of the end and side walls.

If it is desired to lock the parts together I prefer to use a strap 20 fastened as at 21 to one of the side walls and adapted to em brace the box, and having hook ends 22, can be securely fastened together by any desired locking means. I show a strand 23, such as wire or cord, locked by a seal 2%, but it will be evident that I can use any other form of locking means. The strap 20 passes through the slots 21 in the cover and bottom of the box, and when the box is withouta cover, the strap provides the means for lifting the box without pulling it,apart.

In Fig. 5 is shown a modification in which the end 25 of the inner wall is formed with a widened end, and the bottom of the slot 12 is inclined so that the side wall 11 is locked by the end 25 against II'KHVI'I'IOl'lt away from the end wall, which might be i'ieccssary, in case the flanges 18 are low.

These keys of the side walls to I-laving thus descril'icd my invention, what walls and side walls, the side walls having transverse slots 111 their top and bottom edges near their ends, keys embracing the top and bottom edges of'the end walls and entering the slots of the side walls, the keys and the side walls'having eo-acting means for holding the side ails to the keys,'and top and bottom closures embracing the side and end walls at the outside on the top and bottom.
